Nine patients aged over 8 years with developmental dislocation of the hip were treated by an open reduction, femoral shortening and varus derotation osteotomy with or without a Chiari osteotomy. The mean age of the patients was 11.1 years (range 8-17 years), and the mean follow-up period was 7.1 years (range 1-13 years). The left hip was involved in four cases: the right in three and two cases were bilateral. One hip redislocated. The remaining patients recovered nearly full movement of the affected hip. Five out of eight patients had a normal gait without limping or pain. Two others limped secondary to a leg-length discrepancy, which was corrected with leg equalization. The remaining patient had an improvement of her preoperative limp and was pain-free. These results indicate that it is possible to obtain good hip function after open reduction of a developmentally dislocated hip, even after the age of 8 years.
9例8岁以上发育性髋关节脱位患者接受了切开复位、股骨短缩和内翻旋转截骨术，部分患者还接受了Chiari截骨术。患者的平均年龄为11.1岁（范围8 - 17岁），平均随访期为7.1年（范围1 - 13年）。左侧髋关节受累4例，右侧3例，双侧2例。1例髋关节再次脱位。其余患者患髋恢复了几乎完全的活动度。8例患者中有5例步态正常，无跛行或疼痛。另外2例因肢体长度差异而跛行，通过肢体等长矫正得以改善。其余1例患者术前的跛行有所改善且无疼痛。这些结果表明，即使在8岁以后，发育性髋关节脱位切开复位后仍有可能获得良好的髋关节功能。
